  • Pre-emergence herbicide

    Apply pendimethalin 0.75 kg per hectare (2.5 litres per hectare) as pre-emergence on the 3rd day after sowing, mixed with 500 litres of water, using a flat fan (deflector) nozzle. Then irrigate the field, and give one hand weeding on the 30th–35th day. There should be sufficient soil moisture when the herbicide is applied.

    Follow the instructions on the product label. Consult your local Agriculture Officer before use.
